The crown of the moon princess is tainted with the darkness of a soul long since lost to the clutches of evil...

Recruited by Celestia herself to hunt down the helm of her banished sister, Daring Do is in a race against time to save Equestria from certain destruction. An evil organization hell-bent on ending Celestia’s rule by force is hot on her hooves, and a cult of nightmare worshippers assault her at every turn. The return of Eternal Night is a high price to pay for failure, but Daring Do never gives up without a fight!
